编译时出了问题,请大侠帮忙指点一下!

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class MouseTracker extends JFrame
implements MouseListener,MouseMotionListener {

private JLabel statusBar;


public MouseTracker()
{
super("Demonstrating Mouse Event");

statusBar=new JLabel();
getContentPane().add(statusBar,BorderLayout.SOUTH);

addMouseListener(this);
addMouseMotionListener(this);

setSize(275,100);

}



public void mouseClicked(MouseEvent event)

}


public void mouseReleased(MouseEvent event)

}


public void mouseEnter(MouseEvent event)

}


public void MouseExited(MouseEvent event)
{

}

}


public void mouseMoved(MouseEvent event)

","+event.getY()+"]");
}

public static void main(String args[])
{
MouseTracker application=new MouseTracker();
application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

}
编译时出的问题是:
--------------------Configuration: <Default>--------------------
C:\MouseTracker.java:7: MouseTracker is not abstract and does not override abstract method mouseExited(java.awt.event.MouseEvent) in java.awt.event.MouseListener
public class MouseTracker extends JFrame

请大侠指点一下是哪里的毛病?该怎么改啊?

代码太长了点吧！

[hxzg001]

它是说你必须覆盖MouseListener类中的抽象方法mouseExited(java.awt.event.MouseEvent)，我看了你的代码里面实现了一个public void MouseExited(MouseEvent event)，看了是方法名的大小写错了。

[xtyy_2000]

up!!!

[xtyy_2000]

up!!

[hxzg001]

都说你应该把MouseExited()改成mouseExited()了，java的方法名区分大小写的

[xtyy_2000]

这也是个错误.我改过来了还是出现上面那个错误.
我怎么觉得是定义的类或者方法有问题,但有不知道问题到底在哪?
编译显示的是程序第7行有错误,那就是跟"public class MouseTracker extends JFrame"这句有关.
但是看了整个程序也不清楚到底错哪了??

[xtyy_2000]

终于找到错误了,呵呵!原来还有另外2个方法拼写错误.不好意思,结帖!

[hxzg001]

两次错误信息不同的，我已经编译通过了除了上面说的修改，

你要把public void mouseEnter(MouseEvent event)改为
public void mouseEntered(MouseEvent event)

还有要把public void moiseDragged(MouseEvent event)改为
public void mouseDragged(MouseEvent event)
